Previously, when creating a rule to filter tagged container images, you were required to specify a tag value. This made it difficult to select images that were automatically tagged with a computer generated value, a common situation for images pushed to Amazon ECR from a CI/CD pipeline.

Now, Amazon ECR allows you to select all images (tagged and untagged) in a single rule and filter on other image properties without needing to specify a tag value. You can enable this by adding a rule with tagStatus = "Any" for your Amazon ECR lifecycle policies.
